debug_utilities: Create ast_loggrabber
ast_loggrabber gathers log files from customizable search patterns,
optionally converts POSIX timestamps to a readable format and
tarballs the results.
Also a few tweaks were made to ast_coredumper.

+
+ Gathers log files, optionally converts POSIX timestamps
+ to readable format. and creates a tarball.
+
+ Options:
+
+ --help
+ Print this help.
+
+ --dateformat="<dateformat>"
+ A Python strftime format string to be used when converting
+ POSIX timestamps in log files to readable format. If not
+ specified as an argument or in the config file, no conversion
+ is done.
+
+ --timezone="<timezone>"
+ The timezone to use when converting POSIX timestamps to
+ readable format. It can be specified in "<continent>/<city>"
+ format or in abbreviation format such as "CST6CDT". If not
+ specified as an argument or in the config file, the "local"
+ timezone is used.
+
+ --append-logfiles
+ Append any log files specified on the command line to the
+ config file specified ones instead of overriding them.
+
+ --taraball-uniqueid="<uniqueid>"
+ Normally DATEFORMAT is used to make the tarballs unique
+ but if you may want to use your own unique id in the
+ tarball names such as the Jira issue id.
+
+ <logfiles> | <pattern>
+ A list of log files or log file search patterns. Unless
+ --append-logfiles was specified, these entries will override
+ those specified in the config files.
+
+ If no files are specified on the command line the, value of
+ LOGFILES from ast_debug_tools.conf will be used. Failing
+ that, the following patterns will be used:
+ /var/log/asterisk/messages*
+ /var/log/asterisk/queue*
+ /var/log/asterisk/debug*
+ /var/log/asterisk/security*
+
+NOTES
+ Any files output will have ':' characters changed to '-'. This is
+ to facilitate uploading those files to Jira which doesn't like the
+ colons.
